Welcome to Sewer Lair Builder, which is one of the latest Teenage Mutant Ninja Turtles Games we have added on our website, and we really hope that we are making you all happy with the addition of this game, since we have not brought new content in this category of Nickelodeon Games in quite a while, and we know that there are plenty of fans of the show who want to play games with these characters. In this one, the turtles are moving into a new lair, so you will be helping them build it out after which you will send them on a mission to bash baddies. If you want to know how you will do these things, learn from this next part of the description! Add rooms to unlock Turtle tasks and connect them together with pipes. Help the turtles do tasks to fill their power gauge and earn points. Use points to level up your turtles and rooms to improve chances of completing missions. That's the gist of the game which we have just explained, so we now invite you all to start it right now, and we are sure that you will have a really good time with this game, only on our website!
